The first order statistic (or smallest order statistic) is always the minimum of the sample, that is, where, following a common convention, we use upper-case letters to refer to random variables, and lower-case letters (as above) to refer to their actual observed values. See more In statistics, the kth order statistic of a statistical sample is equal to its kth-smallest value. Together with rank statistics, order statistics are among the most fundamental tools in non-parametric statistics See more For example, suppose that four numbers are observed or recorded, resulting in a sample of size 4. If the sample values are 6, 9, 3, 8, the order statistics would be denoted where the subscript … See more Moments of the distribution for the first order statistic can be used to develop a non-parametric density estimator.
